SPECIFICATION forming part of Letters Patent No. 425,321, dated April 8, 1890.

` Application filed June G, 1889. Serial No. 313,380. (No model.) i

To all wiz/0771, t may concern.'

Be it known that I, CHARLES H. HELMS, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and 5 State of New York, have invented new and useful Improvements in Heel-Trimmers, of which the following is a specication.

This invention relates to an improvement in heel-trimmers; and the invention consists rc in the details of construction set forth in the following specification and claims, and illustrated in the accompanying` drawings, in which- Figure l is a side elevation of a heel-trimr5 mer. Fig. 2 is 'an end elevation of a heeltrimmer. Fig. 3 is a plan viewof a heel-trimmer, showing by dotted lines the position of the heel being trimmed. Fig. a is a section along :c fr, Fig. 3. Fig. 5 is an end elevation zo of a heel-trimmer, the guard and stop-guard being removed. Fig. 6 is a detail view of a trimming-knife. Fig. 7 is a detail view of a modified form of trimming-knife. Fig. 8 isa detail view of a guard. Fig. 9 is a detail view of a modified form of guard. Fig. l0 is aplan view of a rand-trimmer. Fig. 11 is an end View of Fig. 10. i Fig. l2 is a detail view, enlarged, of a rand-trimmer on a larger scale than Fig. ll.

Similar letters indicate corresponding parts. The driving-shaft A has pulleys B B, one fast, the other loose, so that by shifting a suitable source of power the shaft can be put in motion or at rest. The shaftAcarriesa knife C, which is slotted for` the passage of its attaching-screw D, so that the knife can be properly adj usted on the shaft. The heel of the boot or shoe is pressed between spring arms or jaws E, provided with pads F, of suit- 40 able material, such as leather or wood, The heel is held in position by the pressure of the pads F on the heel, and the elasticity of the jaws E allows the heel to be turned between the pads F, so that different parts of t-he heel will be exposed to the knife. The knife C is variously shaped, as required by the desired form of the heel, Fig. G showing one form of showing another form of knife, and Fig. l knife. The jaws E are mounted on a support G, having' a slot for the screw H, which secures the support to the main frame I, so that the support can be adjusted as desired. Setscrews K enable the jaws E to be pressed so as to bring the pads F nearer together, if desired.

The top lift of the heel is made of the shape which the heel is to have in cross-section, and said top lift is made to rest against the guide L. By turning the heel with the top lift continuously in contact with the guide L the knife C will trim the heel to the required shape. The guide L has a base or support M, secured by an arm or support N to the main frame. The arm N is slotted for its attaching-screw O, so that the arm N, with the guide L, is adjustable.

To protect the body or quarter of the boot or slice from injuryT by the knife, the guard P is provided. Said guard may be variously shaped, as required. In Fig. 8 is shown one form of guard, and in Fig. 9 is shown another form of guard. The guard of Fi 9 has projecting end portions Q to protect the quarter when the boot or shoe is turned and the heel trimmed to a considerable extent. v

A stop-guard R prevents excessive turning of the boot or shoe. The stop-guard R is slotted for its attaching-screw S, so that the guard R can be properly adjusted. The shaft A, 1n addition to the knife O, can be provided with a rand trimmer or knife T, Figs. l and 5. The guard P and stop-guard R are shown secured to an arm or support U, slotted for the passage of the attachingscrew V, so that thearm U, with the guards P R, can be adjusted. The knives C T are shown secured to a suitable head W, which is wedged or secured to the shaft A, so as to move or turn with said shaft.

The spring-jaws E enable the boot or shoe. to have the heel trimmed after the last has been taken from the shoe, thus enabling the last to be used for making a second shoe while the rst shoe is being trimmed.

The omission of the last is rendered possible from the fact that the spring-jaws E and pads F are so arranged in relation to the rotary cutter C and guards I and R that the pads bearon the heel alone, as in dotted lines, Fig. 3, and since the jaws and pads do not grip or compress any part of the boot or shoe body other than the heel the shape of the boot or shoe will not be aifected by the jaws and pads. Thus the entire boot or slice, eX- cept the heel, is free from pressing` contact with all parts of the machine, in which respect my invention differs from those prior heel-trimming machines which are provided with spring-jaws that press on the quarter. The pads F of the spring-jaws E are arranged at the base or inner end portion of the rotating cutter. C, and the quarter-guard P is located at the outer end portion of the said cutter, in order that the pads may grip the heel alone, while the guard P rests at the base of the heel to protect the shoe body or quarter. The stop-guard R is located directly above the cutter C between the base or inn er end portion thereof and the quarter-guard P, and said stop-guard is above the heel-pads F, and is arched to provide ample room for the cutter C and the cutter-head NV. The stop-guard prevents the boot or shoe upper from coming in Contact with the cutter when the boot or shoe is turned between the heel-pads F to, complete the trimming,r of the heel. The guard R thus acts as a stop-guard, for it prevents any part of the boot or shoe upper f rom coming in contact with the cutter.V

Vhat I claim as new, and desire to secure by Letters Patent, is

l. In a heel-trimming machine, the combination, with a rotating cutter C and a suitable support G, of a pair of spring -jaws mounted on the support and having the gripping end portions located beside and at the inner end portion of the cutter to grip the heel alone and leave the remainder of the boot or shoe free from pressure, substantially as described.

2. In a heel-trimming machine, the combination, with a main frame and a heeltrim min cutter C, of a support G, adj ustably sccured to the main frame and adjustable spring-jaws E, carried by said support, and

having pads F located at the inner end of the cutter, and which grip the heel alone and leave the remainder of the boot or shoe free from pressure, substantially as described.

3. In a heel-trimming machine, the combi-y nation of a rotating cutter C, a stop-guard R, arched above the cutter, a quarter-guard P at the outer end of the cutter, a top-lift guide L at the inner end of the cutter, and springjaws E, having pads F, arranged below the stop-guard at one side of the cutter at the inner end thereof to grip the heel alone between the quarter-guard and the top-lift guide, substantially as described.

4. In a heel-trimming machine, the combination of a rotating cutter C, a stop-guard,

arched above the cutter, a top-lift guide Lv atY the inner end of` the cutter, a quarter-guard P at the outer end of the cutter, and a .pair of spring-jaws E, arranged to grip the heel `alone between the top-lift guide and the quarterguard, substantially as described.

5. In a heel-trimming machine, the combination, with a main frame and a rotating cutter C, of an adjustable arm U, located on the vmain frame and carrying the quartcr-guard `P, and the arched stop-guard R, arranged, re-

spectively, at the outer endand` over the cutter, and spring-jaws E, having pads F, which, grip the heel alone and leave the remainder of the boot or shoe free .from pressure, substantially as described.

It is hereby certified that the nume -of the assignee in Letters Patent No. 425,321, granted April 8, 1890, upon the application of Charles H. Helms, of Poughkeepsie, New York, for :in improvement in n Heel-Trimmers, was erroneously Written and printed Charles N. Gooilseli that said name should have been Written and printed Charles H. Gooclsell, and that the said Letters tion therein that the seme may conform to the record of the ease in the Patent Oce.
